That’s my new favorite.

It’s interesting how the wind appears to spiral into the eye near ground level, and out from the eye at 12k meters.

It’s like there is a toroidal shape where on the bottom, wind spirals in towards the eye, transitions to the top in the eyewall and spirals out at the top.

"rising air in the eyewall follows isolines of equal angular momentum, which [also] slope outward with height" (Wikipedia)
